To all whom 'it may concern: y

^ Be it known that I, WILLIAMv L. Mlcon'rr, a citizen of the UnitedStates, residing at Ann Arbor, county of Washtenaw, State of Michigan,have vinvented a certain new and useful Improvement in Automobiles, anddeclare the following to be a full, clear, and exact description ofthesame, such as will enable others skilled inthe art-to which it pertainsto make and use the same," reference singl had to the accompanyingdrawings, whic form a part of this specification.

M. invention relates to automobiles and Y an'o ject of my improvementsvis to rovide an automobile having an improved orm of runnin -gear andone having a solid driving axle. secure this obj ect in the deviceillustrated'in the accompanying drawings, in y which,- y A Fi re 1, is alan view of the chassis and runnlng-gear o 'an automobile embodying my`invention. Fig. 2, is a plan'view mostly in section, showing the detailsof the apparatus where the power of the engine is 25 communicated to thetransmission shafts.v
